The Indiana Tax Court recently ruled in favor of The University of Phoenix, Inc. (“University of Phoenix”) on an important issue of first impression involving the sourcing of service revenue for purposes of computing Indiana’s corporate income tax apportionment factor. The University of Phoenix, Inc. v. Indiana Dep’t of State Revenue, Cause No. 49T10-1411-TA-00065 (Ind. Tax Ct. 2017). Baker & McKenzie LLP represented the University of Phoenix in the case. The Tax Court held that in sourcing service revenue, Indiana law requires a taxpayer activity/cost-based analysis and rejected the market/customer-based analysis historically advanced by the Indiana Department of State Revenue (“Department”).
